SPRAY-NOZZLE myooaosa.

Specification of Letters Patent.

Patented Nov. 24, 1908.

Application filed May 29, 1907. Serial Ito. 376,254.

I To all whom it may concern:

Be it known that I, ARCHIE-ALI) S. WASH- BURN, a citizen of the United States,and a resident of Germanto'wn, in the county of Columbia and State of New York, have invented a new and useful Improvement in Spray-Nozzles, of which the following is a full, clear, and exact description.

The purpose of the invention is to providea spray nozzle particularly adapted for use in spraying trees, shrubbery, plants, and the like, so constructed that even when the liquid includes a preponderance of paris green, lime, sulfur, etc, there Wlll be but a minimum .tendency to clog, it being possible for the nozzle to be continuously used for a great length of time without the necessity for cleaning the same, the tendency of the nozzle in operating being to free itself of all particles contained in such mixtures.

It is a further purpose of the invention to providea construction of nozzle in which the outlet may be made very large, if desired, and yet wherein most of the liquid will be converted into a fog or mist, the remainder escaping in the form of a spray.

It is also a purpose of the invention to provide a very simple, durable, and economical nozzle, but two pieces being needed in its construction. 3

The invention consists in the novel con struction and combination of parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings formin a part of this speclfication, in which simi ence indicate corresponding parts in all the figures.

Figure 1 is a perspective view of the 1mproved nozzle; Fig. 2 is an enlarged central longitudinal section through the same; Flg. 3 is a transverse section taken practically on the line 3-3 of Fig. 2; and Fig. 4 is a sectional side elevation of the body ortion of the nozzle, the section being ta en practically on the line 4-4 of Fig. 3.

The nozzle consists of but two parts, a

body A, and a cap B for the body. The

body consists of a socket member IO-Which is rendered exteriorly polygonal in order that it may be turned with a wrench, and the said socket member is provided with a threaded chamber 11, the outer end portion 12 of which chamber is plaln or smooth, as

ar characters of refer is clearly shown in Fig. 2, and at the outer end of the socket memberlO, a plug member 13 is formed which is of reduced diameter and exteriorly threaded. This plug member 13 is provided with a conical chamber 14.

that connects with the chamber 11 of the socket. member at the termination of the threads therein, as is also shown in Fig. The plug member is further provided with two passages 15 and 16. The outlets for these passages are (lian'ietrically opposite, as is shown in full lines in Fig. 3, but the said passages as they continue through the said plug member and through the side wall of the conical chamber 14 incline in opposite directions, as is indicated by dotted lines in Fig. 3. Thus it will be observed that the largest possible area of space is provided at. the inlet portions of the said passages 15 and 16. as is best shown at 17 in Fig. 2, and this practical enlargement of the said passages at their inlet ends is to permit the ready escape of small pieces of trash, and the like.

The cap member B has its outer surface 18 milledfor the greater portion of its length so that the said cap may be readily screwed upon the body A, and the cap is provided with a chamber, which at its inner end portion has a thread 19 to engage with the thread of the plug member 13 of the body, as is also shown in Fig. 2, but the upper end portion of this main chamber is given the shape of the frustum of a cone. and its wall is perfectly plain and smooth, as is shown at 20 in Fig. 2, and at the apex of this conical chamber 20, an outlet aperture 21 is made in the outer end of the cap B, which aperture 21 may be of any desired size, large or small, without interfering with the roper operation of the nozzle, and by pre erence the said outlet aperture 21 is surrounded by a guard. rib 22, and a similar rib 23 is formed at the marginal portion of the closed end of the said cap, as is illustrated best in Fig. 1, but it will be understood that the rib 23 may be omitted, if so desired. A suitable washer 24 is made to intervene the cap and the body when the two are connected.

k In 0 eration, a liquid passed out from the body through the two oppositely inclined passages 15 and 16 and ntering the conical chamber 20, is forced to": travel along one or the other side of the said chamber with cen- 21 or apex of the chamber 20 at the opposite side. In consequence, practically all of the liquid is converted by such impingement and such direct motion into a fog or mist. This passage of the liquid through the conical chamber 20 of the cap with centrifugal movement until it strikes the opposite side of the chamber 20 at its apex, causes the powdered substance, such as paris green, lime, etc., to pass along with the fluid and effect an even distribution of the compound upon the branches of the trees without clogging the nozzle; thus all forms ,of disgorging devices are dispensed with. The large area of exposure at the inlet ends of the passages 15 and 16 enables small pieces of trash or small lumps to enter said passages with comparatively little obstruction, whereupon they are forced along to the outlet 21 by the pressure of the incoming liquid.

Having thus described my invention, I claim as new and desire to secure by Letters Patent,-

1. In a spray nozzle, a cap rovided with a conical chamber "the wall 0 said chamber at the apex end being flattened and an outlet extending from the center of said flattened portion through the end of the cap and surrounded at its outer end with a guard, rib, and means for directing the liquid to the side wall of said chamber at opposite points, which means forces the incoming liquid supply to travel along the wall of the chamber and impinge the apex at a side opposite that at which the fluid enters.

2. In a spray nozzle, a body comprising a socket member and a plug 'member, the plug member having a conical chamber closed at its apex and communicating at its base with the chamber of the socket member, the said plug member being further provided with opposing passages, the outlet ends of said passages opening at the outer face of the plug member at diametrically opposite sides of said face, the passages 'incllning rearwardly in opposite directions and opening into the said conical chamber, the passages being of greater area at their inlet. ends, a cap covering the said plugmember and provided with a conical chamber, the wall of the said chamber at its apex end being flattened, and an outlet in the center of said flat wall at the apex of the chamber, the outlets of the plug member being threaded and of reduced diameter and formed at the outer end of the socket member, the said plug member having a conical chamber closed at its apex and connecting at its base with the said outer smooth end portion of the chamber of the socket member, the plug member being provided with passages having their outlet ends opening at the outer face of said plug member at diametrically opposite sides of said face, the said passages extending through the outer wall of the plug member and inclining rearwardly in o posite directions and opening into the sait conical chamber, the said passages being practically enlarged at their inlet ends, a washer surrounding the plug member and engaging the outer end of the socket member, and a cap provided with a chamber having a thread at its inner end portion for screwing on the plug member, the cap when in position engaging said washer, the said chamber of the cap at its outer end portion having the shape of the frustum of a cone, the wall at the apex end of said chamber having a flat face, the cap being provided with an outlet leading from the center of said flat wall at the apex end of the chamber, the outlets of said passages in the plug being directed to the side wall of the conical chamber of the cap.

4. In a spray nozzle, a cap provided with a conical chamber the wall of said. chamber at the apex end being flattened thereby forming an angle at its junction with the sides of said chamber, and an outlet leading from the center of said apex end of the chamber, and means for directing the liquid to the side wall of said chamber at opposite points.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
